Arranged displaceably on a tubular rod I, which is parallel to the axle ofthe-back wheelsvof the frnotor earandis advantageously 4Frlxed by iiatliron -bars between the ends of the chassis or an extension thereof, is a weight member 2 consisting of a cast-iron tube. The weightmember tube 2 is milled to a plane surface at its two ends and is provided at each end with an adaptor 3 which carries slip ring type abutments 4 slidably mounted on the rod I and gives it its exact axial position. The abutments 4 may be made of light metal in a chill mold or the like, so that hardly any machining is necessary. The xing of each abutment 4 to the weight-member tube 2 at each end is effected by means of three screws 5 which are secured against loosening by Seger rings. The abutment 4 receives a felt ring 6 in front of which fle. nach of the adjusting -r'lings pushed fon "the 'tubularfrod's and -fcan be fxed 'in, 3the desired 'positionday-grub screws I5.

'In order 'to-"protect 'the sliding `surfaces l' of ithe anti-zskid f device Afror'ndust land dampness, fthere Yis provided, :at each end of the 4Weightlmerriber,

'agprotecting fdevice Whir'ih-V consists 'essentially of dust/collecting sleeve -I6 Tfanid' of ametallicfcovfering cap il which encloses the latter.

a spring clip 'I is placed as a closure of the bore and as an oil seal. The inner space of the tube can consequently serve for receiving oil or other lubricant which is fed to the inner space through a filling aperture 9 which is provided in the weight member and is closable by means of a screw 8. On the inner end of each of the abutments 4 there is provided a sleeve I0 which is provided with a helical groove I I into Which are screwed turns of a spiral buffer spring I2 which surrounds the rod I. r1`he other end of each spring I2 is screwed on an adjusting ring I4 which is likewise provided with a helical. groove vv-allowsfa'movement o'fdisplacement vofthe vweight v member.

Into each outer end of the tubular rod I, there is inserted a socket I8, the outer part of which is provided with a screw-threaded bore. These screw-threaded bores serve for receiving screws by means of which the whole device is xed to the chassis. A method of fitting the anti-skid device to the chassis is represented, by Way of example, in Fig. 2. f

When the vehicle is travelling, the weightmember swings to and fro under the inuence of the centrifugal forces of the vehicle and the action of the buier springs and always shifts its weight in such a manner that a releasing of the back wheel, which is located in the inner curve, from, the roadway cannot take place, so that skidding of the motor vehicle is eiectively prevented.

What I claim is:

1. An anti-skid device for motor vehicles comprising a straight rod, a hollow sleeve-shaped weight member, a slip ring abutment in each end of said weight member slidably mounting said weight member on said rod, stationary abutments on said rod inside said weight member, buier springs in said weight member surrounding said rod supported by and coacting between said abutments, said weight member and said slip ring abutments completely enclosing said springs and the points of abutment thereof.

2. An anti-skid device for motor vehicles comprising a straight rod, a hollow sleeve-shaped weight member, a slip ring abutment in each end of said weight member slidably mounting said weight member on said rod, said rod extending longitudinally and centrally of said weight member, stationary abutments on said rod inside said weight member, buffer springs in said weight member surrounding said rod supported by and coacting between said abutments, said weight member and said slip ring abutments completely enclosing said springs and the points of abutment thereof.

3. An anti-skid device for motor vehicles comprising a straight rod, a hollow sleeve-shaped weight member, a slip ring abutment in each end of said weight member slidably mounting said weight member on said rod, stationary abutments on said rod inside said weight member, buffer springs in said weight member surrounding said rod, supported by and coacting between said abutments, said springs being in a pre.. stressed condition, said weight member and said slip ring abutments completely enclosing said springs and the points of abutment thereof.

4. An anti-skid device for motor vehicles, comprising a straight rod, a hollow sleeve-shaped weight member, a, slip ring abutment'in each end f of said weight member slidably mounting said weight member on said rod, said rod extending longitudinally and centrally of said weight member, stationary abutments on said rod inside said weight member, buffer springs in said weight member surrounding said rod and extending longitudinally and centrally of said weight member, said buier springs being supported by and coacting between said abutment and being in a prestressed condition, said weight member and said slip ring abutments completely enclosing said springs and the points of abutment thereof.

5. An anti-skid device for motor vehicles comprising a straight rod, a tubular weight member extending substantially over the length of said rod, a slip ring abutment on each end of said weight member slidable on said rod, stationary abutments on said rod inside said weight member, buier springs in said weight member surrounding said rod and supported by and coacting between said abutments, said weight member being carried on said rod by means of said slip ring abutments and said weight member and said slip ring abutments completely enclosing said springs and said stationary abutments.

6. An anti-skid device for motor vehicles comprising a straight rod, a tubular weight member extending substantially over the length of said rod, a slip ring abutment on each end of said weight member slidable on said rod, a felt ring Y in each slip ring abutment sealing up the inner space of said weight member, stationary abutments on said rod inside said weight member, buier springs in said weight member surrounding said rod and supported by and coacting between said abutments, said weight member being carried on said rod by means of said slip ring abutments and said weight member and said slip ring abutments completely enclosing said springs and said stationary abutments.

7. An anti-skid device for motor vehicles comprising a straight rod, a hollow sleeve-shaped weight mem-ber extending substantially over the length of said rod, a slip ring abutment on each end of said weight member slidable on said rod, a exible dust-collecting sleeve mounted on said rod/externally of each said slip ring abutment, and a rigid covering cap secured to each said slip ring abutment and enclosing said dust-collecting sleeve, stationary abutments on said rod inside said weight member, buier springs in said weight member surrounding said rod and supported Yby and coacting between said abutments, said weight member being carried on said rod by means of said slip ring abutments and said weight member and said slip ring abutments completely enclosing said springs and said stationary abutments.
